Èlea is olive tree in ancient Greek. This work is about the passage in which Odysseus and his companions prepare the weapon to blind Polyphemus, after having gotten him drunk. In this painting, Ulysses is at the bottom of the painting, highlighting his look at Polyphemus and the thought that comes out of the central part of his head, that is, the rational one. It is worth highlighting Oliveira’s two saffron bars, which represent the hero’s defense against the monster.
